My dissertation“Empörung und Fortschritt. Grundlagen einer kritischen Theorie der Gesellschaft” (Indignation and Progress.Foundations of a Critical Theory of Society) was published in 2008 and won the Best First Book Award of the German Political Science Association (DVPW).

The English translation "Indignation and Progress" is
forthcoming with Oxford University Press (transl. Ciaran Cronin).

In this book I develop a theory of deontological
recognition that emphasizes the importance of indignation for social movements. I defend the general idea of such a
critical theory against five other strands of social criticismand hereby also provide the first comprehensive discussion of the
crucial differences between the critical theories of Jürgen Habermas and Axel Honneth.

At the moment I am completing a book project on a
theory of legitimate violence.
